Water (ρ=1000 kg/m^3) flows horizontally through a nozzle into the atmosphere under the conditions given below. (assume steady-state flow).
At inlet: A1 = 10^−3 m^2 V1 = 2 m/sec P1 = 3×10^5 Pa(gauge)
At outlet:
A2 = 10^-4 m^2
P2 = Patm
Determine the external horizontal force needed to keep the nozzle
Ans:
